If Nasa had a brain they would have set Curiosity rover down in the bottom of that canyon. It is pretty obvious if there was water and life it would
have been a colection basin for both providing any proof of any life if any on mars.
Just about anywhere in that canyon would yeild more science than all the locations that have landed on to date.
Water runs down hill...duh

It is also pretty likely that there was once water in Gale Crater (Curiosity's landing spot), so that's why NASA chose it. I mean, Curiosity already
found evidence of an ancient creek bed in Gale Crater.
Prior to Curiosity's launch, orbital analysis (from other NASA probes) of the materials in Gale Crater should an abundance of clay, and clay is known
to only form in watery environments -- hence the reason NASA thinks Gale Crater once had water. Also, there are fractures in the higher grounds
around Mount Sharp (the mountain in the middle of Gale Crater) and those fractures show signs of being "cemented" by sediment, and the manner in which
they are cemented strongly indicates the past presence of water.
That indicates that the water in Gale Crater may have been deep enough to cover those highlands -- which means Gale crater could have once been a huge
Furthermore, orbital pictures showed that there seem to be canyons of exposed sediment on the sides of Mount Sharp -- sediment perhaps laid down when
Gale Crater was watery. These exposed sediment layers of strata will probably be accessible by Curiosity, and NASA is planning to explore this
strata, which possible were formed by wet sediment in water.
Here are some articles explaining why Gale Crate is such an exciting landing spot in the search to finnd if Mars could have once supported life:
